Unit Testing

General info

JasUnit is a slim unit testing framework for JavaScript, following the general design principles of xUnit.

For testing your code, JasUnit allows you to: Create test fixtures with any number of test methods; Implement setup() and teardown() methods which are run before and after each test; Specify a namespace for a fixture for easy organisation of tests; Use the default or custom logger (default appends results to a given element); Use assertions from any scope - this isn't necessary or even really advised, but some people prefer it.

A Unit Testing framework focused on simplicity

This is a Unit test framwork especially designed for the React.JS, Babel, TypeScript, Node, React, Angular and Vue projects. It usually worked with Enzyme(Integration testing)
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

JasUnit follows the general design principles o xUnit

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

JasUnit is primarily used to test front-end code and functionality

Yes

You can easily test methods, properties, UI element actions and other front-end functionalities
Server-side
Allows testing the bahovior of a server-side code

No

Yes

Back-end server behaviour also can be tested with Jest much in the same way as the front-end tests.
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

With JasUnit you can Create test fixtures with any number of test methods Implement setup() and teardown() methods which are run before and after each test

Yes

Fixtures are supported, Jest has many helper functions such as: BeforeEach and afterEach If you have some work you need to do repeatedly for many tests, beforeAll and afterAll if you only need to do setup once, at the beginning of a file.
Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.

Yes

JasUnit allow you to create group fixtures

Yes

Jest supports group fixtures
Generators
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.

Mocks
Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)

Yes

It provides inbuilt Mocking capabilities

Jest uses a custom resolver for imports in your tests making it simple to mock any object outside of your test’s scope. You can use mocked imports with the rich Mock Functions API to spy on function calls with readable test syntax.
Grouping
Allows organizing tests in groups

N/A

Yes

You can declare as many test suites as you want. Grouping of tests together is done using a describe block
